I've wondered the same thing as the OP. I've got several 8 lb'ers and none of them come close to filling the jug. I don't really care about uniformity of the containers. I would like to have 1 lb containers, labeled correctly, of the same powder as the 8 lb containers, so I could decant 1 lb at a time and not get out the big jug every time I wanted to charge the measure. I don't know what I could do about the surplus powders.
